CAS No.: 7784-27-2
EC No.: 233-401-6
Impurities: Trace hydrated forms or residue from packaging and transport
Inhalation: Move individual to fresh air, support breathing with oxygen if needed, seek medical attention if symptoms persist.
Skin Contact: Remove contaminated clothing, rinse skin with flowing water for 15 minutes, wash with mild soap, call physician for irritation or burns.
Eye Contact: Flush eyes with clean water continuously for at least 20 minutes, lift eyelids to remove particles, consult an ophthalmologist immediately.
Ingestion: Rinse mouth with water, do not induce vomiting unless instructed by a medical professional, call poison control.
Medical Attention: Always have emergency medical facilities ready, especially for chemical burns or respiratory distress.
Suitable Extinguishing Agents: Water spray, dry chemical powder, foam approved for chemical fires
Unsuitable Media: Avoid CO2 stream on pure chemical, it boosts release of oxides.
Unusual Fire Hazards: Material acts as an oxidizer; enhances combustion of other materials; releases toxic gases—nitrogen oxides and aluminum oxides.
Protective Equipment: Full protective clothing, self-contained breathing apparatus required.
Fire Response: Remove all combustibles fast, contain runoff to prevent contamination.
Personal Precautions: Evacuate non-essential personnel; use proper PPE—gloves, goggles, mask.
Environmental Precautions: Prevent spillage from entering drains, soil or waterways by building dikes or using absorbent materials.
Cleanup Methods: Scoop up and place in secure, labeled containers; ventilate area; neutralize residue with sodium bicarbonate; dispose through approved chemical waste program.
After Cleanup: Wash area thoroughly, monitor air for dust particles.
Handling: Work in a ventilated space; use spark-proof tools; keep away from incompatible materials like organic matter and reducing agents.
Storage: Store in tightly sealed containers, dry location, separate from combustibles and moisture sources.
Storage Conditions: Cool, dedicated chemical cabinet; no exposure to sunlight or open flames.
Special Requirements: Label containers daily; train staff on oxidation hazards.
Occupational Exposure Limits: No OSHA PEL exists; ACGIH TLV for soluble aluminum salts uses a threshold of 2 mg/m³.
Engineering Controls: Fume hood, local exhaust systems, emergency wash stations.
Personal Protection: Nitrile gloves, safety goggles, chemical-resistant clothing, NIOSH-approved respirator for dust or fumes.
Workplace Hygiene: Remove PPE and wash thoroughly after handling; no food or drink in work area.

Solubility in Water: Easily dissolves; forms clear, colorless solution
Melting Point: 73°C (decomposes)
Density: 1.72 g/cm³ at 20°C
pH (100g/l, 20°C): About 2.5
Decomposition Temperature: Above 135°C, breaks down, releasing toxic fumes
Chemical Stability: Stable under standard storage; decomposes under heat, light, or moisture.
Incompatible Substances: Reducing agents, combustible materials, organic chemicals, strong alkalis.
Hazardous Decomposition Products: Nitrogen oxides, aluminum oxides.
Reactive Properties: Strong oxidizer, can initiate or intensify fire with flammables.
Routes of Exposure: Inhalation, ingestion, skin contact, eye contact
Acute Effects: Severe irritation to mucous membranes, potential for corrosive burns to eyes and skin, respiratory distress on inhalation.
Chronic Effects: Prolonged or repeated exposure can impact respiratory tract, skin, and may trigger allergic reactions.
Toxicological Data: LD50 (oral, rat): approx. 3671 mg/kg; direct eye exposure may result in blindness.
Symptoms: Coughing, difficulty breathing, abdominal pain, redness, burns.
Environmental Fate: Dissolves fully in water, can contribute to aluminum toxicity in aquatic environments, adverse pH shifts.
Aquatic Toxicity: Toxic to aquatic organisms, especially in concentrated spills; disrupts fish gill function.
Persistence and Degradation: Not persistent, but aluminum accumulates in sediments.
Precautions: Never dispose into water bodies or soil without treatment.
Waste Treatment Methods: Gather remaining solids and contaminated materials, label as hazardous waste, do not flush to sewer.
Disposal of Containers: Triple rinse, render unusable, use licensed chemical disposal contractors.
Recommended Practices: Follow local, regional, and national regulations for hazardous waste; maintain waste manifest.
Environmental Protection: Avoid release to environment or landfill.
